Could he go to the Staples that is right across the street instead? They have the Sony 50pks for $14.94, and are more likely to be Taiyo Yuden (top-notch). Tell him to look for the 8x+R Made in Japan.
The 100pks at Compusa are either Sony D11's (made in Tawain) for the 8x or Sony D21's (made in Japan) for the 16x. The 8x+R MIJ 50pks will be YUDEN T02's, probably the most widely used DVD+R in the world. I personally have 1000+ of these discs and the only problems I have had out of them are my error, not the discs.
By the way, I live just outside of Nashville, that's how I know that the Staples is across the street.
If possible email him this pic so he knows exactly what to look for (sorry it's a little blurry)
